Manual kinect skeleton using kmean plug ins, crazy?

Hello all,
I want to use the elliott woods calibration projector patch (openni node under 26b).
But I would need to track the skeleton with this same node openni.

would it be possible to determine a manual skeleton using kmean from vux ?
Would you think it would be a crazy idea ?

any tips would be appreciated;

easier would be just to implement skeleton into the OpenCV-compatible OpenNI nodes / MSKinect

would it have some start points doc somewhere to do this? completely beguiner to this.
